To all whom it 771(61/0011607-"71! Be it known that LQJENs P. Annnnsnn, citizen of the -United States, residing at Brooklyrnin the county of Greenand State of Wisconsin, have invented anew and useful Bob-Sled, of which the following is a specification. I v

The invention relates to improvements in bob sleds. i i

The object of the present invention is to improve the construction of bob sleds, more especially that .shown and described in an application filed by me on the 8th day of April, 1914, Serial No. 830,557, and to pro- 8 is a detail sectional view on the line 88 vide a simple, practical, and eiiicient bob sled of strong and durable construction, adapted to P81111113 a free rocking movement of the" runners in passing over uneven ground. v I

A further object of the invention is to i1nprovethe construction of the means for operating the front runners, which have inde pendent horizontal pivotal movement, and

enable the sled to be easily turned without liabilityof tipping over.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion,

size and minor details of construction, within the scope of the claims, be resorted to Without departing from the spirit or sacrificing any of the advantages of the 1nven tion.

Fig. 3 is a bottom plan viewfof the front portion of the bob sled. Fig. 4. is a vertical longitudinal detail sectional view through the front bolster, knee and runner. Fig. 5 is a transverse sece tional detail view of the bolster, kneie and runner. Fig. 6isa vertical longitudinal sectional view through the rear portion of the,

bob sled, illustrating the construction'for securing the rear runners to the rear bolster.- Fig. 7 1s a transverse sectional detail view" through theibolster, knee andrunner. Fig.

ofFig 2, Fig. 9 isadetail sectional view on the line 9-9 of Fig. 1. Fig. 10 is a .byfront and rear cuffs, 6 and 7. The front reach section 4: is superimposed upon the rear reach section 5, and the front cuff 6-, which is secured to the front end of the rear reach section 5 by a bolt or other suitable means, loosely embraces the front reach'section 4: and is provided at the top with a perforation 8' adapted toregister with perforations 9 of the front reach section 1 in which a pin 10is received to secure the reach sections 4 and 5 in their adjustment. The pin 10 is secured to admin or other flexible con- I nection 11, which has its other end attached to the bob sled. The rear cufi 7, which is bolted or otherwise secured to the rear end of the frontreach section, slidably embraces the rear portion of the rear reach'section.

The front reach section 4; is rigidly connected with the front bolster 1 by upper and lower plates 12 and 13. A flange 14: of the upper plate 12 is connected to the rear face of the front bolster, and the lower plated?) is provided at its front end with a pair of forwardly diverging terminals 15 which are secured to the lower face of the front bolster. The rear portion of the reach section 5 eX- tends beneath t-he bolster ,2 and is loosely connected and suspended therefrom by a' I hanger 16, consisting of a body portion 17 bolted or secured to the upper face of the rear section 5 and provided at opposite sides with depending flanges 18 which embrace the side edges of the rear reach section. The

hanger 16 is provided at the front and back of bodyportion 1'1 with upwardly extend ing ears or flanges 19, arranged on opposite sides of thebolsters and loosely connected with the same'by a bolt 20 or other suitable fasteningdevice, the bolt 20 fitting loosely in theears l9 and the bolster to allow the I reach to receive a rotary movement.

"Thefrear-bolster is supported at ltsends I by knees 22, constructed of suitable metal and consisting of oppositely inclined front and rear sides 23 connected at the top by an arched or curved portion 24. Stationary bearing blocks 25, preferably of malleable castings, are connected to the lower sides of the bolster 2 and are provided with recesses 25 in which the arched or curved portions 24 are received. Pins 26 pass through the ends of the blocks 25 and beneath the knees 22 for fastening the knees to the bolster.

Cotter pins 26 pass through the pins 26 to hold them in place. The lower ends of the inclined sides 23 have terminal attaching portions .27 which engage the top and a side ofthe runners 21, and are bolted .or otherwise secured to the runners.-

Thefront bolster 1 is supported by knees 28 mounted upon runners 2,9 and composed of oppositely inclined sides 30 and curved or arched top portions 31 connecting the sides.

. Connected to the underside of the bolster 1,

and at the opposite ends thereof, are plates 32. A hearing block 33 is connected to each plate 32 by a stud or rivet 34 which permits the bearing block 33 to rotate upon the plate 32. The bearing blocks 33 are recessed,

" as at 35 for the reception of the arched portions 31 of the knees 28. Pins 36 pass through the ends of the bearing. blocks and beneath the knees 28 for fastening the knees to the bearing blocks. Cotter pins 37 pass through the pins v36 for holding the pins in position. a

Bearing blocks 33 per it theinnners 2:9

7 to have an oscillatory movement in a vertical or horizontal plane, while the bearing blocks of the knees for limiting the oscillatory movement of the knees in a vertical plane.

The inclined sides 30 are provided at their lower ends with attaching portions 38, the

attaching portions being secured to the upper faces and sides of the runners.

The front runners 29 are equipped at their front ends with vertical pivots 39, preferably consisting of bolts passing through metallic straps a0 and 4:1. The metallic strap 4L0 is bent approximately U-.sha-,pe,, and extends around the front end of each front runner, is disposed longitudinally of the same and is secured at its terminals to the upper and lower faces of the runner. The ether metallic strip l-. hich is also beat ietearnrernaately ushers, :is

disposed transversely of the front end of the front runner and extends across the same and is secured to the side faces thereof, as clearly illustrated in Fig. 9 of the drawings. Each pivot bolt 39 is provided at its lower end with a head 42, which is arranged in a recess 43 in'the front end of the front runner, and a nut 4C4 engages the upper face of the transversely disposed metallic strap and firmly clamps the straps between it and the head onithe bolt. 'The said metallic straps i0 and d1,- form caps which reinforce the front portion of the front runners and firmly support the pivots 3.9 in'a vertical position. t

The vertical pivots 39 pass through open ings 4-5 in the terminal portions of a trans verse connecting bar or member 46 which;

connects the forward ends of the runners together, and connected to, the bar 4.6 ,iS a

draft bar or member 47. The transverse connecting bar 46 which is preferably constructed of flanged metal, has the terminal portions 48 of one of the wings or flanges thereof flattened, and the flattened portions of the connecting bar are retained on thevertical pivots d5 by nuts 49 or other suitable fastening means. The transverseconnecting bar 46 causes the runners to turnin unison on the vertical stems or pivots34,

w ich connect the knees 28 with the bolster The yoke is also connected to the transverse bar or member l6 by a vertical pivot bolt passing through the transverse plate 53 and the connecting bar or member 46, and

also piencing bearing disks or plates56 i57 constituting a fifth wheel and secured re spectively .to the bottomplate 53 of the yoke and to the transverse bar or member d6. The rear end ,58 of the bar 50 is bent downwardly and extended through an opening 59 of a link 60, which is adjustably secured to the front reach section at the lower face thereof by a vertical pivot bolt 61. The link 60 is provided with a plurality of openings 62, adapted to receive the pivot bolt 61 to permit a downward or forward adjustment of the link which connects the'rear end of the draft bar or member 47 to the frame of the .loob sled. The front portion of the link .60 is bent downwardly and ofiset from the lower face aQf the bottom plate 13 or the tract reach section and the re r e d 5 9f he said ar 59 is Secured in the spell;

The sides of the yoke are 1,182,128 r V l 3 ing on the link by a key 63 or other suitable fastening device, a washer 64 being pref erably interposed between the key and'the front portion of the link.

A tongue or pole 651sp1voted at its rear end within the yoke 51 by a bolt 66 located in rear of the bottomplate 53 which reconnected with each other by a substantially I front runners pivotally connected to the- V-shaped connecting rod 67, composed of forwardly converging sides connected at their front ends by an eye 68 which is linked into a loop 69 depending from and carried by the front portion of the rear section 5 of the reach. The rear ends of the sides of the V-shaped connectingrod 67 are provided with eyes 70 which are linked into eyes 71 projecting from the inner faces ofthe rear runners 21 at the front portions, thereof. The eyes and the said loop constitute pivotal connections so as not to interfere withthe rocking movement of the rear runners.
